[WIP] Add support to cloud_init to add win_init.

win_init will add the ability to do some initialization to windows based AMIs.
Add support to Change the Administrator password - todo: still need to encrypt this.
Add support to enable WinRM - todo: need to update this to enable winrm over https instead (or as well).
